Title: Method for leak detection in a pipeline system.
Inventor: KLOCKARS CARL-ERIK
IPC: G01M/
Filed: 1985-12-16
Abstract: Method for leak detection in a pipeline system, more particularly in a water supply and sewer system. The purpose of the invention is to efficiently and with great accuracy determine the scope and location of damages in the line system. For this purpose leakage indicating means are employed that comprise tracers, which are supplied to the water running through the pipes, each pipe being supplied a special tracer. Samples are taken at certain points downstream in the system. These samples are analysed and the concentration of tracers is determined. Using the concentration figures, the inflow of tracers from adjacent pipes can be established, in respective pipes. Thus, an estimation of the leakage from and to each pipe can be made.

Abstract: L'appareil d'ostomie comprend une plaque de contact (22) ayant une surface interne, une surface externe opposée et une ouverture (40) engageant la surface interne. La plaque de contact possède des canaux de sortie d'écoulement communiquant avec l'ouverture et engageant la surface externe pour permettre aux déchets de stomate de s'écouler du stomate au travers de la plaque de contact. Un agencement d'étanchéité à rainures (90, 92) fixe le réceptacle à la plaque de contact. Un écran de protection du stomate (38) ayant une surface de protection interne adaptée pour être placée face à l'utilisateur et une surface de protection externe est positionable de manière que la surface de protection interne se trouve au-dessus de l'ouverture et espacée d'une petite distance par rapport à la surface interne à l'écart de l'utilisateur, définissant ainsi une chambre de protection adjacente au stomate. L'écran protecteur protège le stomate lorsqu'un objet touche la plaque de contact à un endroit au-dessus du stomate. L'écran protecteur peut être retiré de la plaque de contact pour permettre une irrigation au travers de cette dernière. On peut créer un vide dans les chambres de la plaque de contact pour que cette dernière adhère au corps.

Abstract: Circuit de protection contre les surtensions dans des systèmes de communication servant à protéger les équipements contre les fuites de courant provenant des lignes électriques. Un circuit de verrouillage temporisé (60) est utilisé pour activer une pluralité de SCR de commande (42, 43, 45, 47) qui "pincent" la surtension. L'utilisation d'un circuit de verrouillage pour activer l'agencement de commande, au lieu de la technique conventionnelle consistant à utiliser un courant de ligne de surtension réelle, permet d'utiliser des dispositifs moins encombrants, ce qui permet de réduire aussi bien les dimensions du circuit que la dissipation de puissance de ce dernier.

Abstract: Successive sheets are drawn from a magazine by a gripper which is movably mounted on a drum-shaped rotary conveyor and serves to transfer successive sheets into a gathering machine. The position of the gripper with reference to the conveyor is indicative of the thickness of the sheet or sheets which are transported from the magazine, and such position is ascertained by a monitoring device in cooperation with an input element which is movable with the gripper. The input element can constitute a soft iron core which extends into a coil of an oscillatory circuit constituting the monitoring device, a plate which extends between the plates of a capacitor forming part of the monitoring device, or an arm for a disc bearing encoded information which is monitored by a photoelectronic transducer. The monitoring device transmits signals to a circuit which is adjacent the path of movement of the gripper and includes the transducer or a winding cooperating with a winding of the oscillatory circuit. Signals from the winding or from the transducer are processed by an evaluating circuit and are used to regulate the speed of the conveyor.
